ShareMeNot

Protecting against tracking from third-party social media buttons while still allowing you to use them

Did you know that buttons like these allow Facebook, Google,
LinkedIn, and others to track your online browsing activities on every
site that includes one of these buttons, even if you never click the
buttons and (in some browsers) even if you have third-party cookies
disabled?

ShareMeNot is a browser extension designed to prevent third-party buttons
(such as Facebook's “Like” or Twitter's “tweet” button) embedded by sites across
the Internet from tracking you until you actually click on them. Unlike
traditional solutions, ShareMeNot does this without completely removing the
buttons from the web experience.

Note that this extension is part of a research project and not targeted for
general use. We welcome your feedback and will use
it to improve our tool.

As of July 20, 2014, ShareMeNot is no longer being maintained as a standalone tool.

We're excited to announce that we have incorporated ShareMeNot's functionality
into the Electronic Frontier Foundation's Privacy Badger tool, and
we recommend that all ShareMeNot users transition to using Privacy Badger.
